might sound counter intuitive, but I've stopped running GFO and only skimming 4 days/week. My chalices and blastos in particular have benefited from some "trash" in the water.

The params youbhave listed did not give nitrate andphos readings but with GFO running your tank sounds a little too clean for chalices. Unless your alk was high, I'm going to say its lack of nutrients as well.

I'm thinkin that to I'm goin to stop running the phos

Chalices are LPS corals so they like more nutrients in the water. They also like to be feed as well.

Ok so I was pullin my hair out tryin to figure out why all my corals r dying and the only thing I can come up with is my room filters r shot the test meter is reading .004 where is a good place to buy the filters and do I need to change all of them

But now that the road has been running it's down to .002
